Technical Field

[0001] The utility model relates to the technical field of key switches, in particular to a sealed key switch. Background Art

[0002] A push button switch is an electronic component that uses a case to push a transmission mechanism to connect or disconnect the moving contact and the static contact and realize circuit switching. It is an electronic component that can open a circuit, interrupt current, or cause it to flow to other circuits.

[0003] However, due to the gap between the key and the housing, most existing key switches do not have good protection effects. The dustproof and waterproof effects during normal use are relatively general, which greatly limits the occasions where they can be used. In addition, the overall fastening structure mostly uses threaded fasteners for alignment installation, which makes the overall disassembly operation more troublesome, making it difficult to completely replace the internal components and perform regular maintenance operations.

[0004] Based on this, the present invention proposes a sealed key switch to solve the above problem. Utility Model Content
